- this doesn't do the lookup **yet**
- while here, refactor setConfigurationMap so it reads like a story,
with chunks bitten out into a handful of static inline void methods.
- read the *region* and *zone* settings; this duplicates what
the ViewStep does and is currently unused, but ..
- add new support for using the system's TZ (rather than
the fixed values from *region* and *zone*). This complements
GeoIP lookup.
This is the actual feature that started the long rewrite of
the Config object (so that all the business logic would be in
one place, usable for both widgets and QML).
FIXES#1381
- allow finer-grained control over whether-or-not to adjust the
timezone in the live system.
- handle some special cases at the point of loading-configuration.
- document the setting in locale.conf
- correct some documentation bugs
- adjust the YAML schema for locale.conf so it's legal YAML syntax
**and** validates the current file.
- remove the weirdly-structured prettyStatus and similar:
the Config object has human-readable status strings (three,
for location, language, and LC-formats) which can be
normal properties with signals.
- Implement prettyStatus in the view step by querying the Config.
- the language and LC settings migrate from page to config
- add API for explicitly setting language (which is then preserved
when clicking new locations)
- since Config knows what settings there are, it should create the
jobs to run later -- not the Page.
- this doesn't work yet, because the Config does **not** know what
the selected timezone is yet.
The Config object wasn't being used at all in the locale module;
reset it to empty and start using it in locale, so that
configuration functionality can be added to it as-needed,
and with the necessary refactoring built-in.
